Install Synaptic and view these packages and send a screenshot of that. Alternatively, you could just replace command-line apt-get with synaptic.

Arpit, thanks, but the point of the question is not to install another package -- this is a server, and ideally it should not be running a window manager to begin with, and should have as few non-standard packages installed as possible.

I just wanted to see the problem in visual form. I'm sorry I'm not that familiar with the server platform. Anyways, I'm happy that the problem is solved. Btw, don't forget to mark this as solved.
